[Feature Request] Add 320 kbps option for M4A/AAC audio

[ghost]

I think it would be nice if you could set the bitrate of the AAC audio to 320kbps, which is generally considered the sweet spot for quality and size.

by the way, this is an excellent recorder as-is, so thank you for making this

Thanks! Will consider adding 320kbps bitrate with next releases.
